Norman RobbinsSlaughterhouse

Synopsis

In the Lovecraft Room of "Usher", his great country house, aging horror star
Romney Marsh has gathered together a group of theatre people, ostensibly for
a read through of a new play. When the last of his guests has arrived, however,
Romney instructs the gatehouse keeper to let loose the guard dogs in the grounds.
With a moat full of piranha fish, Romney is confident that his weekend guests
are caught like rats in a trap. It seems that someone has been sending him
newspaper cuttings about the suicide thirty years ago of Mabel Monk, an actress
with whom Romney had an affair, and he intends to find out who is responsible.
But before he can, Tanya, one of the actresses, is found with her throat cut,
and shortly afterwards Romney himself dies, poisoned by one of his own chocolates.
Marooned in the house, with thick fog swirling outside, the other guests soon
realise that the murderer must have some connection with the deceased Mabel Monk,
and as the action progresses, the finger of suspicion points at each of them in
turn, until the final truth is revealed, with fatal consequences.
